Seattle City Light believes a raccoon wandered into the a substation at 8th Avenue NW and Leary Way and somehow de-energized the system. The incident caused a string of feeder lines to fail, causing the outage.
After nearly two hours in the dark crews were able to restore power to all affected customers by 5 a.m. The raccoon was never captured but is said to have survived. http://www.king5.com/news/local/seattle/raccoon-de-energized-...
